Celebrity dating 101: Your car can become the perfect date spot.

Moon Hee Jun, leader of 90s K-pop group H.O.T., has revealed that during the height of his fame he would secretly date girls in the back of his car.

"I had to date in secret during the H.O.T days, so I dated secretly in the car," he said on the December 27 episode of KBS2's Happy Together. "I used the back part of the front car seat as a table. If you put in [$150USD] more it would become an automatic system like those used in in-flight meals on the plane."

The 34-year-old went on to say: "I set up a movie projector to the ceiling of my car. With enough window-tint the back turns into a movie theater. Meals would be prepared beforehand and then we would share it on cute character plate."

Alsa, none of his relationships stood the test of time. "You get tired of things after a while," the single star revealed. "The longest relationship I had was a year."
